QuestionAnswer
electromagnetic waves radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge
medium An intervening substance through which something else is transmitted or carried on
waves with lowest frequency Radio waves.
waves that are detectable by human eyes Light waves
waves that cause sunburn ultraviolet light (the UV ray)
waves that penetrate skin and muscle but stopped by lead shields? x-rays
wave with the highest frequency gamma rays
reflection as the bouncing back of a ray of light into the same medium, when it strikes a surface.
refraction The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density
interference The variation of wave amplitude that occurs when waves of the same or different frequency come together.
law of reflection The angle of incidence is always equal to the angle of reflection
scattering The dispersal of a beam of particles or of radiation into a range of directions as a result of physical interactions.
angle of incidence is the angle measured from the ray to the surface normal.
angle of reflection is the angle measured from the reflected ray to the surface normal.
incident ray is a ray of light that strikes a surface.
reflected ray is the ray that represents the light reflected by the surface
